STEAM-COOKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 329,024, dated October27, 1885.

Application filed December 3, 1884. Serial No. 149,433. (No model.)

.T0 all whom it may concern:

Be it known that I, ROYAL E. DEANE, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Steam-CookingApparatus, of which the following is a description.

This invention relates to apparatus for cooking articles of food bysteam heat; and it has for its object a simple, inexpensive, andefficient device by means of which the various modes of cooking-such asboiling` baking, roasting, broiling, Sic-may be practiced.

The invention consists of novel features of construction andcombinations, to be hereinafter described, and claimed in the clauses atthe close of this specification.

In the accompanying drawings, Figure l is a vertical section of myimproved steam-cooking apparatus. Fig. 2 is a similar view showing thecounterpoised lid raised from the cooking-chamberrIhe same letters ofreference are used in both figures to designate corresponding parts.

The cooking-Vessel may be of any preferred shape or size, and the partsmay be cast or formed` of sheet metal.

The bottom A of this vessel is constructed with double walls a a', whichform a steamspace, A', the bottom wall, a', being tted to receive asteam-supply pipe, s, and an exhaust-pipe, e. This exhaust-pipe e shouldbe located at the lowest point in the wall a', (though not so shown inthe drawings,) in order to carry off'all water of condensation formed inthe steam-space A'. The bottom A is provided with an outwardlyprojecting flange, cito which the upper portion or body, B, of thevessel is secured. This body B is also formed with double walls b b',forming a steam-space, B', entirely independent of the steam-space A inthe bottom, and is fitted to receive a steam-pipe, s', and anexhaust-pipe, e. For convenience and economy,I prefer to connect thesteamsupply pipes s and s' to a steam-supply pipe, S, common to both,and also connect the exhaust-pipes e and e' to an exhaust-pipe, E,common to both, the pipes s s and e e being each tted with suitablevalves to open or close communication between the steam-spaces A and B'and the steam and eX- haust pipes S E, in order that the steam-supplyand exhaust of each of these steam-spaces may be entirely independent ofeach other.

To draw off the liquid contents of the vessel, I provide a pipe, F,leading from thelowest point in the upper wall, a, of the bottom, saidpipe being provided at a suitable point with a cock, f, as shown.

The lid D is preferably hollow and is hinged to a bracket, b2, securedto the exterior wall, b', of the body B of the vessel. `The hingestrap dprojects a distance beyond the hingepintle, and to its outer end issecured a weight or counterpoise, C, which serves to prevent the lid,when open, from falling.

It will be seen from the foregoing description that upon opening thecocks in pipes s and e steam will be admitted to space A', thus heatingonly the bottom of the vessel, and that upon closing said cocks andopening the cocks in pipes s' and e steam will be admitted to space B',thus heating the body of the vessel. When it is desired to heat theentire vessel, all of the cocks above named are opened to the properextent.

I do not limit myself to any particular form of Vessel, or to thedetails of construction, as

many changes may be made therein without departing from the principle ofmy invention*- as, for instance, the steam-spaces A' and B might be madeproportionally smaller.

I claiml. A steam-cooking apparatus consisting of a vessel provided withdouble walls forming two or more independent steam-spaces, whereby thedifferent portions of the vessel may be heated separately orsimultaneously, substantially as described. l

2. In a steam-cooking apparatus, the combination, with the vessel havingdouble walls forming two or more independent steamspaces, of independentsteam and exhaust pipes for each of said spaces, substantially asdescribed.
